Ingestion plan based on table uniqueness

ABSTRACT

Embodiments of the present invention disclose a computer program product for processing tabular data. In various embodiments, an electronic document is received through a network, along with associated metadata. A plurality of table markers, or tabular data markers, are identified, in response to analyzing the received electronic document for said markers. References and citations associated with the plurality of tabular data markers are identified. A graphical representation of the relationship between identified tabular data markers and the identified references is generated. A uniqueness score is calculated, based on the generated graph and an ingestion plan is generated for the received electronic documents based on the calculated uniqueness score value.

BACKGROUND

The present invention relates generally to the field of table ingestionfrom documents, and more particularly to the optimization of theingestion of tables from a document using data and metadata analysis todetermine uniqueness.

Data analytics examines data in order to draw conclusions about theanalyzed information. Data is commonly presented in tables and may makedirect analysis more complex. For many domains such as science,medicine, and finance, context for tables may be as critical tounderstanding the data as the data itself. Difficulty in processing, oringestion, tables may come from a document or set of documentscontaining tables with various formats or styles. Tables analyzed usingOptical Character Recognition (OCR), or Object Linking and Embedding(OLE), may contain errors in the data conversion.

Ingestion of well-defined HTML tabular data may be less costly andresource intensive than the ingestion of a pictorial table ingested viaOCR extraction. If there is a document with a combination of formats, aningestion system may need to defer to the well-defined tabular data toensure quality, wherein this may not yield the most desirableinformation, as a table with a less common or less well-definedformatting may contain desirable information within the context of thedocument.

SUMMARY

It would be advantageous to have an ingestion plan for tabular data thatidentifies high value data, regardless of format or error potential,before ingestion. Embodiments of the present invention disclose acomputer program product for processing tabular data. In variousembodiments, an electronic document is received through a network, alongwith associated metadata. A plurality of table markers, or tabular datamarkers, are identified, in response to analyzing the receivedelectronic document for said markers. References and citationsassociated with the plurality of tabular data markers are identified. Agraphical representation of the relationship between identified tabulardata markers and the identified references is generated. A uniquenessscore is calculated, based on the generated graph and an ingestion planis generated for the received electronic documents based on thecalculated uniqueness score value.

With increasing data consumption, organization of data in tables maybecome more prevalent. As data consumed for organization, for example,via a server, and stores data, for example, in a database, theorganization of consumed data may become more time and resourceintensive. Organization of consumed data may be more efficient usingdata tables and it may be advantageous to engage in a system forprioritizing table and associated data by the importance of the data, asin various embodiments of the present invention.

Information may become more cloud based, and various formats, styles,file types, etc. may be used to represent data in tables. Increases indata may increase the time and resources needed for the analytics oftabular data. Traditional techniques of tabular data extraction usingOCR or natural language processing may be time, cost, or computerresource prohibitive. It would be advantageous to go beyond dataextraction to optimize and prioritize high value tables with unique datathat can minimize redundant extraction and processing.

Embodiments of the present invention may utilize a query answeringsystem that may identify structured information in received tabular datain documents. The tabular data may be analyzed to identify and analyzereferences and/or citations within the document referring to the tabulardata. The number of references may correspond to a predetermineduniqueness criteria which may be used to determine an ingestion plan forthe tables identified within the received documentation. Depending on auser's desired data the ingestion plan may be modified.

Embodiments of the present invention will be described with reference tothe Figures. Referring to FIG. 1, a general distributed data processingenvironment 100 is illustrated, in accordance with an embodiment of thepresent invention. Distributed data processing environment 100 includesserver 110, client device 130, and data store 140, all interconnectedover network 150.

Network 150 may include permanent connections, such as wire or fiberoptic cables, or temporary connections made through telephone orwireless communications. Network 150 may represent a worldwidecollection of networks and gateways, such as the Internet, that usevarious protocols to communicate with one another, such as LightweightDirectory Access Protocol (LDAP), Transport Control Protocol/InternetProtocol (TCP/IP), Hypertext Transport Protocol (HTTP), WirelessApplication Protocol (WAP), etc. Network 150 may also include a numberof different types of networks, such as, for example, an intranet, alocal area network (LAN), or a wide area network (WAN).

Each of server 110 and client device 130 may be a laptop computer,tablet computer, netbook computer, personal computer (PC), desktopcomputer, smart phone, or any programmable electronic device capable ofan exchange of data packets with other electronic devices, for example,through a network adapter, in accordance with an embodiment of theinvention, and which may be described generally with respect to FIG. 4below. In various embodiments, server 110 may be a separate server orseries of servers, a database, or other data storage, internal orexternal to client device 130. Data store 140 may be any computerreadable storage media accessible via network 150. Data store 140 mayindex received electronic documents to be communicated to client device130, in accordance with an embodiment of the invention.

Client device 130 may act generally to host an application, capable ofdisplay in a graphical user interface, or GUI, or communicate over anetwork, for example network 150, via a web browser. In variousembodiments of the invention, client device 130 may act generally toreceive input from a user, communicate user input to data store 140 forfurther processing, and communicate with server 110 over a network 150.

Client device 130 may be able to communicate with server 110 and datastore 140 over network 150. Client device 130 may receive documents,tabular data, user inputs, analytics outputs, or other communicationsfrom server 110 or data store 140, as described below, in accordancewith an embodiment of the present invention. In various embodiments,client device 130 may display electronic documents, tables, ingestionplans, or other information to a user in a GUI and receive input toannotate one or more parts of the GUI in an interactive manner. Forexample, an interactive selection tool may be provided to the user toallow the user to select one or more graphical representations ofanalytics, described in more detail below. The user may make a selectionthrough clicking an input device, for example, a mouse, or anyappropriate manner of gestures, touches, combined keys, or any othermeans of interactive input with the client device 130, as described inFIG. 4.

Server 110 includes ingestion application 120, as described in moredetail in reference to FIG. 2. In various embodiments, server 110operates generally to receive inputs, process a set of receivedelectronic documents based on the received inputs, communicate analysisresults, for example, ingestion plans, for display to a user device, forexample client device 130, and host applications, for example ingestionapplication 120, which may process and/or store data.

Ingestion application 120 may be, for example, database oriented,computation oriented, or a combination of these. Ingestion application120 may operate generally to receive and process electronic documentsfrom a client device, for example, client device 130. Received documentsmay contain tabular data of various formats, for example, XML, HTML,PDF, various pictorial data, etc.

Ingestion application 120 may receive a set of documents from clientdevice 130 or data store 140. Ingestion application 120 may analyze thereceived document or set of documents in order to extract any tabulardata within the document(s). Received documents may include metadatathat identifies the provenance information for each correspondingdocument, for example, the source URL, title, author(s), publicationinformation, etc. Extracted tabular data may be indexed or stored in adata store in memory for later processing. Ingestion application 120 mayanalyze the non-tabular data of the documents in order to determine ifthere is any references, citations, identifying metadata, authorshipinformation, etc., or generally “references,” which correspond to theextracted tabular data. Ingestion application 120 may generate arelationship graph based on the tabular data and references in which thetables are vertices and the documents are edges, where, the number ofreferences affect amplitude. Ingestion application 120 may analyze therelationship graph and determine a uniqueness score based on therelationship graph. Ingestion application 120 may display tabular data,above a predetermined uniqueness score, to a user or generate aningestion plan based on the uniqueness score.

Referring to FIG. 2, FIG. 2 is a functional block diagram illustratingthe components of ingestion application 120 within the distributed dataprocessing environment 100 of FIG. 1. Ingestion application 120 includesreceiving module 200, analysis module 210, relationship module 220, anddisplay module 230.

In reference to FIGS. 1 and 2, receiving module 200 may act generally toreceive inputs from and/or a document or sets of documents from adevice, for example, client device 130 or data store 140. In anembodiment of the present invention, receiving module 200 may receive adocument, for example an article about the United States Census, andprovenance information, for example, embedded links, source URL, andother metadata, along with a query, or other instruction, from a userfor an ingestion plan for the United State Census article. The query mayinclude a uniqueness threshold value that may be communicated torelationship module 220, described in greater detail below. Receivingmodule 200 may communicate the received document or set of documents,and provenance data, to analysis module 210 for further processing orstore the received document or set of documents in a data store.

Analysis module 210 may act generally to analyze received documents,search received documents in order to identify table markers associatedwith tabular data within the received document, and analyze the receivedprovenance data for references, citations, identifying metadata,authorship information, etc, or “references” associated with theidentified table markers.

Analysis module 210 may use traditional techniques to load documents inmemory, for example, Apache POI, Apache UIMA, Apache ODFDOM, OCR, orother methods. Analysis module 210 may identify table markers bysearching for HTML based document markers, for example, <TABLE>, orother formats which has a designated tabular structure. For example,OOXML data may be embedded in XML format or in OLE tables which can beidentified by the following example:

<table xmlns=“http://purl.oclc.org/ooxml/spreadsheetml/main” id=“1”name=“MarginTable” displayName=“MarginTable” ref=“D3:G6”totalsRowShown=“0”> </table>In an additional example, analysis module 210 may receive a PDF documentand use common spacing, headers, breaks, structured columns, or otherborders to identify tables within the document. Analysis module 210 maycommunicate index identified tabular data and associated references,along with the corresponding document, to be stored in memory orcommunicated to relationship module 220 for further processing.

Relationship module 220 may act generally to generate a relationshipgraph based on received tabular data, document, and references. Thegenerated relationship graph may include tabular data as vertices,documents as edges, where the edges are directional indicating areference to tabular data. In an embodiment, edges may be annotated, forexample with column or row labels in pivot format. It can be appreciatedthat the relationship graph described above is merely exemplary andother graphical formats may be used to demonstrate the relationshipbetween the tabular data and associated references graphically.

In various embodiments, user delay or resource limitations may prevent afull document from being communicated to relationship module 220 beforethe relationship graph is generated. If tabular data or a reference isadded to the relationship graph and the corresponding document has notbeen loaded a provisional edge or vertex may be added to therelationship graph represented a potential associated document andcontain an indicative label as provisional.

In an embodiment relationship module 220 may analyze the relationshipgraph based on the topology sorts, edge threshold, or graph density, inorder to determine a uniqueness score. A uniqueness score may becalculated based on: the number of inbound directional edges to a vertexor specific reference (topological uniqueness score); a predeterminedthreshold of outgoing edges in order to determine if tabular data isunique or not relative to other tabular data (edge threshold uniquenessscore); or a predetermined threshold number of vertexes indicating acluster of related tabular data (graph density uniqueness score). Invarious embodiments a uniqueness score may be associated with tabulardata and may indicate value or importance to a user. Relationship module220 may communicate tabular data and the associated uniqueness score todisplay module 230 for display to a user, for example, via client device130.

In various embodiments, the uniqueness score associated with tabulardata may be increased or decreased (weighted) based on secondaryfactors, for example, overlapping or repetitive tabular data or metadatawithin a document. Relationship module 220 may generate an ingestionplan based on the uniqueness score associated with tabular data whichmay be communicated to display module 230.

Display module 230 may act generally to communicate generatedrelationship graphs, ingestion plans, or tabular data, to be displayedto client device 130, through network 150, and receive input from a uservia client device 130. Display module 230 may receive communicationsfrom relationship module 220, for example, a relationship graphcommunicated from relationship module 220. In various embodiments,display module 230 may receive user input, for example, selectingtabular data for ingestion or a uniqueness score threshold, which may becommunicated to relationship module 220.

FIG. 3 is a flowchart depicting operational steps of ingestionapplication 120, on a server computer within the data processingenvironment of FIG. 1, in accordance with an embodiment of the presentinvention. Referring now to FIGS. 1, 2, and 3, in step 300, receivingmodule 200 receives documents from a client device, for example, clientdevice 130, or a data store, for example, data store 140, via server110. The documents may be in electronic format, for example, HTML, XML,or OCR extracted.

In step 310, receiving module 200 receives provenance informationassociated with the received documents. Provenance information mayinclude source URL's for the documents, the authorship information,author(s), the title, publication information, or other metadataassociated with the received document. In various embodiments thedocuments and provenance data may be indexed and stored in a data store.

Receiving module 200 communicates the received documents and provenancedata, if available, to the analysis module 210 which analyzes thedocuments, in step 320, and identifies tabular markers in order toidentify tabular data within the received documents. Analysis module 210analysis the document and provenance data for references or citationsrelated to the identified tabular data, in step 330. References can comefrom table of contents, table of tables, title information from theprovenance metadata, or version dates to identify the most recenttabular data. In various embodiments natural language searches may beperformed in order to identify and categorize the uses of identifiedtabular data, or identify textual context for the tabular data, forexample, differentiating data tables contained within sections of thedocument identified as “prior art” or “related background” vs. sectionsof the document identified as “Experiments” or “Findings”. Naturallanguage analysis may also be used to identify statements within thedocument referencing the tabular data, for example, “Our findings areshown in the above table X.”

Analysis module 210 communicates documents, identified tabular data, andidentified references to relationship module 220 and, in step 340,relationship module 220 generates a relationship graph based on thereceived documents, tabular data, and references. As described above, invarious embodiments, tabular data is used as vertices, documents areedges, and the references are directional edges.

Relationship module 220 generates a uniqueness score for the tabulardata based on the relationship graph in step 350. As described above theuniqueness score may be based on the number of inbound directional edgesto a vertex or specific reference, a predetermined threshold of outgoingedges in order to determine if tabular data is unique or not relative toother tabular data, or a predetermined threshold number of vertexesindicating a cluster of related tabular data. A uniqueness score may beweighted based on the number of references in a document associated withtabular data.

In step 360, relationship module 220 generates an ingestion plan basedon the calculated uniqueness score. In various embodiments relationshipmodule 220 communicates the ingestion plan to display module 230 fordisplay to a user, as described above. In additional embodiments,relationship module 220 may store the ingestion plan in a data orcommunicate with a module or application within server 110 and processthe tabular data based on the generated ingestion plan.
